# Fillers Method
This method is on par with the No-Sand Method in terms of quality of finish but is a slightly slower process. However, it is faster than hand-sanding or using a Dremel to post process your prints. Relevant PPE such as a mask and gloves should be used when utilising this method.

### Materials
* High-cover aerosol paint + primer (such as Rustoleum 2X)
* Acrylic or enamel fast-drying spray putty (such as Superfine High Build Filler)
* Isopropyl wipes or similar to clean parts
### Method
1. Ensure that your printed parts are clean and dry, **wipe the parts** down with Isopropyl wipes or a similar product and let dry.\
2. Begin by applying a **thin coat** of high-cover spray-putty to the parts. Note that the spray-putty may cause blotching to your surface if applied too thick or unevenly across your surface.\
3. Wait **30-45 minutes** (or as instructed on bottle) between coats.
4. Re-coat your parts a total of **3-5 times**.\
5. Once you have applied all the necessary coats (according to how smooth you would like the finish of your surface) leave your parts to **dry overnight**. The spray-putty will fill up the gaps between the prints' layers and level your surface smoothly.
6. Apply a **medium coat** of high-cover spray paint to your part.\
7. **Wait 10 minutes** between applying your paint coats.
8. Repeat the painting process **3-5 times** as necessary.\
9. Wipe your parts clean and you are ready to go.
